Washing pools is used
in plastic waste washing such as bottles (PET),
film (pre-cut in a guillotine) etc. Other application is also the
treatment of the sinking fraction of the float/sink-process. The
washing is caused by injected water
and the mutual friction of the plastic particles.
Axial rotating screwprevent the plastic particles
to stick to the side
walls of the drum.

The process is
that the material is loaded from the top and after the
washing cycle discharged. The residual humidity is about 20 % so
that the material must be dried.

The washing water is
discharged through the bottom of the drum. A sieve separates the
material from the residues of the washing process. The water
is
recirculated through filter set which is cleaned
periodically.
